The emergence of LCC(Low Cost Airline), airline companies have begun to unbundle their service offerings by introducing ancillary fees for airline services that were provided as free. So this study examined the effect of acceptability of airline service additional charges on negative emotion(betrayal and anger) and customer behavior. This study used AMOS ver 18.0 for analyzing hypotheses. To provide a detailed picture of results and to test hypotheses comprehensibly, split calculations in a step-by-step analysis. Hypothesis 1, 3, 4 was partially supported. But hypothesis 2, 4, 6 was totally rejected. The seven items which we choose are baggage charges, reservation change charges, food and beverages, seating and comfort, in-flight entertainment, Wifi, airport lounge charges included. Findings identify the strongest effects on betrayal in the case seating and comfort, followed by baggage charges, airport lounge charges, reservation change charges, food and beverages in order.

국내 6차 산업의 발생배경은 농·수·축산업의 시장 확대라는 측면에서 시작되었으나, 외국형 6 차 산업에 대한 일방적 모방과 1차 산업 의존형 발전전략으로 발전 한계에 이르고 있다. 이에 6차 산업이 발전하게 된 배경과 6차 산업에 대한 접근의 문제점을 파악하고 이를 바탕으로 하여 서비 스 유통적 관점에서의 6차 산업의 발전에 관한 정책방안을 제시하는 것이 본 논문의 목적이다. 6차 산업의 정책적 한계로는 1차 산업 위주의 정책으로 인한 부가가치 감소, 농산품 위주의 산 출물, 정부주도적 관점, 그리고 소비자와의 커뮤니케이션 부족 등으로 정리할 수 있다. 6차 산업은 1,2,3차 산업의 특성을 모두 함께 지니고 있으나 그 동안의 연구들이 6차 산업에 집중하여 1,2,3차 산업 각각의 특성을 간과한 것이다. 6차 산업 이전에 각각의 산업을 구성하는 요소들을 파악하고 접근해야 하는데, 이는 단순히 1차 산업 확대가 아닌 창출하고자 하는 서비스 전략에 맞는 1·2차 상품 개발 전략을 병행해야 할 것이다. 이에 본 연구에서는 6차 산업의 구성요소를 살펴보고, 선 행연구 분석을 통해 제시된 전략들에 대한 점검을 토대로, 서비스 유통 관점에서 6차 산업정책의 발전방안을 제시하고자 한다.
The background of the 6th industry in Korea started from the aspect of expanding the market of agriculture and fishery industry, but it is reaching the development limit by unilateral imitation of foreign 6th industry and development strategy of dependent on 1st industry. The purpose of this paper is to examine the background of the development of the 6th industry and the problems of access to the 6th industry and to examine the development of the 6th industry from the viewpoint of service distribution. The policy limitations of the 6th industry can be defined as primary industry oriented policies, agricultural oriented policies, government - led policies, and lack of communication with consumers. Although the 6th industry has all the characteristics of the 1st, 2nd and 3rd industries, the researches concentrated on the 6th industry and overlooked the characteristics of each of the 1st, 2nd and 3rd industries. Before the 6th industry, we must identify and approve the elements that make up each industry. Instead of simply expanding the primary industry, the first and second product strategies should be followed in accordance with the targeted service strategy. In this study, we examined the components of the 6th industry and examined the strategies presented through the analysis of previous research, and suggested the development strategy of the 6th industry in terms of service distribution.

The purpose of this study is to find out the features of the Korean family change since 2,000 and to interpret the meaning of the change on the basis of the critical review of both the positive perspective and the negative perspective of the family change in Korea. Through the method of the literature review and the analysis of the various statistics by KOSTAT, it is drawn that explaining the change only by “diversity of family compositions” is not enough to figure out the meaning of the family change in Korea today and that it is needed to go further to approach the change as disintegration of the ‘nuclear’ composed of the married couple and their children. It is also drawn that the disintegration has led to weakening of the long term functions by the family, i. e., the function of life and of the virtues, which shakes the way of human life and the order of our society. Therefore, the present family change in Korea is to be understood as crisis, not as progress. And it is recommended that the family politics in Korea is to be focused on the ways for the healthy functioning and rebuilding the nuclear of the family.

본 연구는 국가의 하위 단위인 지역단위에서 지역 간 경기공행성을 분석하는데 그 목적 이 있다. 연구의 분석을 위해 통계청에서 공식적으로 발표하는 지역내총생산 자료를 이용하 여 이동상관계수 산출을 통한 인접한 지역 간의 경기가 함께 움직이는지를 분석하였다. 분석 의 결과는 지역 간 경기 공행성이 존재하는 지역은 수도권, 호남권, 대경권 등이었으며, 충청 권과 동남권은 경기 공행성이 존재한다고 보기 어렵거나 약화되는 것으로 나타났다. 그러나 이러한 결과는 지역별, 시기별 차이가 있는 것으로 나타났다. 지역간 경기 공행성에 대한 분석은 기존의 경기변동 및 공행성의 원인 분석에서 얻을 수 없었던 지역간의 경기 움직임에 대한 새로운 정보를 제공하고 산업구조 변화에 따른 경기변 동의 특성을 파악함에 있어 새로운 경기대응책을 수립하는데 기여할 수 있다. 또한 경기 공 행성 분석을 통한 경기변동 과정에서의 비대칭적 특성을 줄 일 수 있는 대안을 마련할 수 있 다. 이에 따라 지방자치단체는 경기변동에 따른 지역별 경제적 손실을 고려한 지역경제정책 을 모색해야 할 것이다. 또한 지방자치제 부활을 통한 지역의 특성을 고려한 경제정책 시행 이 가능해짐에 따라 경기순환 과정에서 변동성을 줄이기 위한 지역경제정책 방안이 증가할 것이다.
This study aims to analyze the interregional business cycle comovement at the regional level, which is a sub-unit of a nation. For the study, official regional GDPs, released by the National Statistical Office, were used to calculate the mobile correlation coefficient in order to observe whether economies of neighboring regions move together. The results of the analysis showed that the business cycle comovement areas were the metropolitan area, Honam area. Chungcheong area and Southeast area was found to be difficult or weaken view that there is a business cycle comovement. However, these results show that there are regional and seasonal differences. The analysis of interregional business cycle comovement could provide information on the economic movements in the region and special features of economic fluctuation, led by a change in the industrial structure, that could not be obtained from the existing analysis of economic fluctuation and business cycle comovement, in turn assisting with the establishment of new countermeasures against the economic fluctuation. In addition, it could help find an alternative measure to minimize the asymmetric feature of the economic fluctuation. Therefore, it would be helpful for local governments to pursue regional economic policies that are devised in consideration of regional economic loss led by economic fluctuation. Moreover, there would be a growing number of regional economic policies in order to reduce volatibility in the economic cycle since it is possible to conduct economic policies accounting regional features due to the resurgence of local autonomy.

병력관리는 군 사고예방은 물론 전투력 보존 및 발휘의 핵심이다. 그러나 예측하지 못한 시간과 장소에서 생각지도 못한 부대원이 사고를 유발하게 되면 경험 없는 초급간부들은 당황하며 어떻게 처리해야 할지 몰라 전전긍긍할 때가 많다. 뿐만 아니라 각종 사고를 예방하는 것도 군의 존립의 이유인 전쟁에서의 승리를 위한 전투준비태세 완비의 전제 조건이다. 이 막중한 임무의 최전선에 초급간부들이 있다. 그러나 전투준비를 위한 제반업무에 만전을 기하여야 할 시 간도 부족한데 병력관리에 대한 상급부대의 지시와 요구되는 수준은 경험이 부족한 초급간부들에게 많은 스트레스를 주는 것이 사실이다. 그래서 초급간부를 위한 군 상담모델을 연구하게 되었다. 초급간부 군 상담모델을 적용하여 상담 을 진행 하면 가장 신속하고도 효율적으로 상담대상에 대한 파악이 가능하다. 효율적인 상담은 깊이 있는 내담자의 이 해가 선행되어야 한다. 누군가를 심층 있게 이해한다는 것은 많은 노력과 시간을 필요로 하는 행위이다. 그러나 초급간 부들은 그러한 시간과 노력을 충분히 투자할 수 있는 여건이 미흡한 것이 사실이다. 그러므로 초급간부 군 상담모델을 적극 활용하여 선택과 집중을 통한 상담활동을 지속한다면 효과적인 상담 및 사고예방까지 가능할 것이다.
Soldiers management is the core of military combat power to preserve and accident prevention. But in unforeseen times and places did the unthinkable soldier causes an accident, the inexperienced primary officer were upset, and can often be quite nervous. And various accidents prevention is also win the war, the reason for existence in the military for combat readiness as a precondition for perfection. There are primary officers at the forefront of this critical mission. However, in spite of the lack of time to work for combat readiness, orders from higher units of troops management and that’s level giving a lot of pressure to primary officer. So I made the primary officer military counseling model ike this. Using Primary officer counseling model is possible to rapid and efficient counseling advice against the target client soldier. The efficient counseling is must take precedence on understanding on client soldier deeply. Depth understanding someone needs a lot of effort and time. However, to Primary officer, it is true that they have a lack of condition that are enough to give the time and effort. Therefore, effective counseling and accident prevention is possible to use counseling model through choice and concentration activities.

When using the original Angio Intervention, one had to put Guide wire, Catheter on patient's leg so that there were curves according to patients and the possibility of patients moving made it inconvenient to proceed. Thus, by making supplementary tool shaped of table, it minimized the inconvenience of patients and operator, increasing the convenience of the process and thereby evaluating the utility and its usefulness. The main material of supplementary tool was used with cost efficient Fomax material, and by considering the patient's lower limb, and the length of tools when doing Angio Intervention, it was made as 1300mm, 600mm at the front, 500mm at the back. Also, considering the weight of the tool, it was manufactured with thickness of 5mm and 10mm with the same design, and evaluated by using survey of 14 medical personnel using the tool in A University Hospital, Daejeon. When manufacturing and using supplementary tool, it became heavier as the thickness increased. Whereas, the thinner, the lighter the tools were, however, had unstability which cause lack of safety. Despite the fact, they responded that they had more convenience of using 5mm and 10mm tool compared to when they did not have at all, and through this, we could evaluate that the use of supplementary tool is useful to the procedure. Accordingly, when doing Angio Intervention, we could find out that it is useful to use the supplementary tools, and by reducing the weight and increasing the safety, if we can make use of this kind of supplementary tools, it would be more useful to the procedure.

Because the lens is a tissue with the highest sensitivity, the lens shielding is very important in CT imaging. However, in clinical terms, there is a lack in the efforts in decreasing dosage on the lens, and the shielding of dosage and the effects on the imaging are researched using bismuth to evaluate the usefulness. As results of the dosage evaluation results, when there is no gantry angle when the thickness of the lens shielding material is 0mm, the dosage was 28.476mGy, and when there is gantry angle, the dosage was 20.852mGy that it was confirmed that the dosage was 27% lesser with gantry angle. It was confirmed that the dosage value decreased with the increase of thickness of lens shielding material when there is gantry angle, and when the lens shielding material was 1mm, the dosage decreased by approximately 39% compared to when it was 0mm. When there is gantry angle, the dosage values were respectively 12.788mGy and 12.776mGy for the crystalline lens shielding material thicknesses of 0.75mm and 1.0mm. In image analysis, the quantitative evaluation and the qualitative evaluation were almost constant regardless of the thickness of the lens shielding material. The optimal lens shielding material thickness to minimize the does of lens and increase the value of diagnosis in Brain CT examination is 0.75mm. Therefore, if this is utilized for easier use in clinical practices, it is considered to be able to contribute to not only the protection of the lens but the accurate diagnosis of diseases.

We performed the quantitative analysis using MATLAB for slice thickness, spatial resolution, and low contrast resolution with the 50 received images which have suitable judgement by scanning AAPM phantom using GE, PHILIPS, SIEMENS, and TOSHIBA. Slice thickness and spatial resolution were measured by using full width at half maximum(below FWHM). Spatial resolution was confirmed that FWHM interval more than 1.0 mm size. Low contrast resolution was measured that how close by using Roundness Index(below RI) until 6.4 mm size. The spatial resolution 9 images and low contrast resolution 10 images which have disapproved judgement were also had the quantitative analysis. The statistic analysis was judged to have statistically significant differences when p-value is less than 0.05 through SPSS statistics 19.0 and T-test (paired t-test). For slice thickness 5 mm, the average qualitative evaluation group shows 4.98 mm and quantitative evaluation group shows 5.02. For slice thickness 10 mm, the average qualitative evaluation group shows 9.98 mm and quantitative evaluation group shows 9.86. No significant differences (p=0.07, p=0.06) with 5 mm and 10 mm. It confirmed the interval for all FWHM until 1.75, 1.50, 1.25, 1.00 mm as approved images on spatial resolution ,and the average distance was 0.102 mm and the minimum distance 0.054 mm. For disapproved images, all interval was not showed under 1.00 mm. For low contrast resolution, spproved image’s RI value shows average 0.81 and minimum 0.77. The disapproved image’s RI average shows 0.70. Statiscally significant differences were presented (all p<0.05) following hole size.

In this study, mammography was conducted with Lorad Selenia from HOLOGIC. The phantoms used were Female rando phantom from THE PHANTOM LABORATORY and ACR phantom from GAMMEX RMI. The dosimeters used were the glass dosimeter reader FDG1000 and PLD from CHIYODA TECHNOL. The shielding used to compare and determine the amount of scattered ray in this study were lead shielding gear with a thickness of 0.25mm from INFAB and a customized bismuth shielding with a thickness of 0.2mm(2 layers of 0.1mm). The conditions were 28kVp, 65mAs for CC view and 30kVp, 85mAs for MLO view. The exposure dose by scattered ray were measured from thyroid, breast on the opposite side and gonad (hereafter called critical organs) without any shieldings for the first experiment, then measured four times each with lead shielding for the next experiment, and measured four times each with bismuth shielding for the third experiment. The average dose for each critical organ without shieldings were 135.75μGy, 649.67μGy and 546.25μGy, With lead shielding, the numbers were 0μGy, 63μGy and 1.5μGy, and 6.25μGy, 12.25μGy and 26.5μGy with bismuth shielding. Therefore, the lead and bismuth shielding have reduced 95.364% and 93.550% of exposure dose. Use of shielding s during mammography reduces the exposure dose on critical organs and other organs of the patient, and despite the similar shielding rate, the new shielding using bismuth is useful in shielding thyroid and gonad considering the mobility of the patient, light weight and thickness of the shielding.

The number of CT gradually tends to increase, but radiation exposure includes higher exposure dose of patients than other test methods as the rate of 67% in the whole radiology tests. Exposure dose of patients has increased due to it and the second exposure has been done by scattered rays of other organs except for test sites. Especially, special shielding has not been done in gonad which is very sensitive to radiation in brain and chest CT. So this study tries to research the second exposure dose of the gonad and how to shield it in Chest CT which does not include it. It was intended for 20 male adults who are 30 years old and conduct chest CT. SIEMENS’s SOMATOM DEFINITION AS* was used as CT equipment. For the scanning conditions, The tube voltage is 120kv, the tube current is 90mAs, and the slice thickness is 3mm as the general chest CT conditions. CHIYODA TECHNOL CORPORATION’s FGD1000 was used as Glass dosimeter (PLD). A lead pad of 0.25mmPb was produced as the shielding board. For the research method, the shielding rate was compared by measuring exposure dose of the gonad before and after shielding and the usefulness of the shielding board was evaluated. The average exposure dose of symphysis pubica before shielding was 280.5μGy and the average exposure dose of coccyx was measured as 151.5μGy. The average exposure dose of symphysis pubica after shielding the gonad with a lead pad of 0.25mmPb was 42μGy and the average exposure dose of coccyx was measured as 41μGy.

The study was conducted from July 5th to 12th, 2014 on 30 males and females. The examination device used for this study were Discovery XR656(GE Healthcare, Kemath, Germany) DR and SOMATOM definition AS+ CT. T he device was made of foamex (foam PVC). The posture for cubital tunnel view examination requires for patients to bend their elbows more than 60 degrees and turn their forearms 20 degrees externally. The analysis method of cubital tunnel depth(CTD) was to measure the length between the deepest location of groove for ulnar nerve and a line vertical to the line connecting protruding part of medial epicondyle and trochlea medial in order to measure the CTD with and without the assistance device. CTD were measured and compared from VRT images on CT examination of 30 males and females to prove the usability of the assistance device. For statistics, SPSS 18.0 version was used to conduct independent two samples t-test. Differences in CTD between the two sexes were nonexistent but, the differences in CTD according to the use of assistance device were 4.63±0.86mm in temporizing measure, and 6.01±0.27mm with the assistance device for male. For females, the results were 4.58±0.41mm in temporizing measure and 5.94±0.58mm with the assistance device. The results proved that the measured values of CTD are deeper with the use of assistance device. The difference between CTD value from CT of normal person and CTD level measured with X-ray using the assistance device were nonexistent. P<0.05) Use of an assistance device made more accurate and convenient examinations possible compared to examinations without any assistance devices. Use of the assistance device in this study in radiological examinations on Cubital Tunnel Syndrome would provide more accurate and convenient examinations in the future.

환자안전 문화에 대한 종합병원 방사선사의 인식을 조사하여 방사선사의 환자안전관리를 위한 기반을 제공하고 안전 활동을 위한 프로그램을 개발하는데 기초자료로 제공하고자 한다. 환자안전 문화에 대한 종합병원 방사선사의 인식을 조사하여, 본 연구의 조사기간은 2012년 6월 13일부터 6월 20일까지 대전광역시 소재 5개 종합병원에 근무하는 방사선사들을 대상으로 198명의 자료를 분석하였다(SPSS 19.0v). 환자안전 활동에 영향을 미치는 요인을 부서 내, 직속상관, 의사소통, 의료사고, 병원 별, 환자안전도에 대한 안전문화와 보고된 사고, 위험하다고 느끼는 환자 안전사고, 가장 많이 발생한 환자 안전사고를 평가한 결과 의료사고 보고체계에 따른 환자안전 문화에 관한 인식에서는 근무기간 25년 이상에서 가장 높게 나타났고 환자안전도 평가에서는 근무기간 10년 ∼ 15년에서 가장 높게 나타났다. 그러므로 종합병원 방사선사의 환자안전문화를 개선하기 위해서는 충분한 인력 배치, 환자안전문제에 대한 적극적인 접근, 그리고 안전사고의 재발 방지를 위해 방사선사의 근무기간을 고려한 임무 부여 등으로 체계적인 의료사고 보고 체계를 활성 시켜야 할 것이다.
Patient safety culture for the general hospital to investigate the perception of radiological technologists, managing of the patient safety provides the Foundation for the safety activities as a basis to develop a program for providing. Patient safety culture for the general hospital to investigate the perception of Radiological technologists, the duration of the survey of the study on June 13, 2012 to June 20, and five general hospitals worked on Radiological technologists workers were material and analyzed the target of 198 (SPSS ver. 19.0). Patient safety activities within the Department, the factors affecting direct care, communication, medical malpractice, hospitals rated, safe for the patient safety culture and the reported accidents, dangerous and caused an accident, most feel that patient safety incident reporting system according to the results of evaluating medical accidents patient safety culture regarding recognition, work appeared in more than 25 years, even the most highly evaluated, the working period of 10 patient safety to 15 years the most highly. Therefore, General Hospital, Director of the patient safety culture improvement of radiation in order to have sufficient staffing, aggressive approach to patient safety issues, and safe working period of relapse prevention of accidents to the radiation as well as giving systematic consideration of mission medical accident reporting system will be active.
